In the mountains behind Tianfeng Academy, in a small cabin.

In the humble hut, on the stone bed, Feng Qing'er was lying on it with a peaceful face, and her face at this moment was a little paler compared to yesterday.

On the futon on the ground, Gray Yuan meditates like a stone sculpture.

"Elder Taishang, I'm here!"

Cao Yu's voice came from outside the door.

"Come in!"

As soon as Cao Yu entered the door, he saw Feng Qing'er, and the joy that he had just made a windfall disappeared in an instant.

The beloved is unconscious, and the longer the time passes, the greater the danger, and he feels that the burden on his shoulders is heavy.

"I have explained to her the old woman in this girl's family, you still have to look for those medicinal materials, so let's leave as soon as possible!"

Gray Yuan glanced at Cao Yu and said lightly.

"Elder Taishang's kindness boy is unforgettable! I'm afraid you still need to bother during the time I'm out."

Grateful from the bottom of his heart, Cao Yu saluted respectfully and thanked him.

"There is no need for this, I have spared no effort to help you to help the academy, I just hope that you are not a wolf-hearted person!"

Gray Yuan is very straightforward, for him, there are not many years left, and he just hopes to find a support for Tianfeng Academy.

"Elder Taishang, if you have something to say, you might as well say it directly, boy, if you can help, you will never shirk it!"

Cao Yu didn't want to be helped for no reason, but he couldn't do anything.

"The request is also very simple, I am old, I don't have many years left, I just hope to find someone to trust for the college when I am dying"

"Simply put, it's the future patron saint of the Heavenly Wind Academy!

Gray Yuan seemed to be entrusting the future, and his voice was low and solemn.

"Elder Taishang, don't worry, the academy treats me like a dear relative, this is my home, and I will definitely protect it."

Cao Yu said solemnly.

"I'm relieved to have your words!"

"In addition, you can call me Gray Lao directly in the future!"

Gray Yuan smiled with satisfaction, and then looked at Cao Yu suspiciously.

"Where did you get the martial arts you just used?"

Cao Yu smiled knowingly, knowing that he couldn't hide it, and he didn't plan to hide it.

"This is from our academy's Gongfa Hall!"

"Didn't you just come out of there, how could you cultivate so quickly!"

Gray Yuan had ten thousand whys in his heart, those martial arts in the Key Exercise Hall had already been rummaged through by these old guys, how could they not find such a powerful martial art.

"Gray Lao, the kid has some unique skills, plus he has good talent, and he quickly understands it!"

Cao Yu smiled mysteriously.

"What's unique?"

Gray Yuan is full of curiosity about this kid who has surprised him several times.

"This martial art is a special language portrayal, if you don't understand it, you will naturally leave out this good thing"

"Special language?"

"That's right, I don't know exactly where the language is, it just so happens that there are books related to this language in the kid's family, and you can read one or two when you have nothing to do."

This situation is stunned, and Gray Yuan lived a lot of age, but he didn't expect it to be another language.

The Xuantian Continent basically speaks one language, so the source of this martial art must belong to other continents.

In this way, it is not surprising that Cao Yu is the only one who can discover this martial art.

"Your family actually has books in languages from other continents?"

Only then did Gray Yuan remember another key point that Cao Yu said.

Hearing this, Cao Yu was full of black lines.

In fact, where does he know any other continental dialects, it is completely blind, and it can't be said that he has the magical treasure of the Chaos Library.

For Cao Yu, the secret on his body is the most important, and no one can tell him unless he has to, after all, this is related to his life.

Who knows if a terrifying being will suddenly search for people related to him, so the safest thing is to keep his mouth shut.

Right now, in order to fulfill this lie, he has to tell a lot of lies!

"Don't hide it from the gray elder, the kid heard what the elders of the family said, a long time ago, the kid family was the existence of the top of the continent, but the middle way declined, so he knew some secrets of the continent!"

As soon as these words came out, Gray Yuan looked at Cao Yu with wide eyes.

Cao Yu didn't know this lie, and inadvertently explained his talent and terrifying combat power.

"It used to be a family at the top of the continent! No wonder you are so terrifying, maybe you are an atavist!"

Gray Yuan's words made Cao Yu look confused, where did he come from.

But he can only calculate it, lest he need more lies to fill in if he says anything more.

"Maybe! I will translate this martial art to the gray elder, if there is a suitable disciple who can teach it!"

Cao Yu said as he handed a jade slip to Gray Yuan.

"Boy, your future is limitless, but your temperament is too sharp, you must collect it when you should collect it, otherwise it will be too rigid and easy to break!"

Ash Yuan looked at Cao Yu with satisfaction.

"Boy, follow the admonition of the gray elder!"

"There's something I want to tell you!"

"When you go out on this trip, the academy can't help you, you have to rely on yourself, I told you about the general news of those medicinal materials!"

"The Blue Leaf Empire is the most advanced empire in the Southern Regions, you must keep a low profile when you go, there are many high-ranking officials and nobles walking on the streets, and there are also a lot of powerful children."

"At the same time, if you want to go to the Blue Leaf Empire's teleportation array, only the Imperial City has it, you have to go there! I will send a message to the old ghost Qin in the Imperial City, and ask him to make it convenient for you!"

Gray Yuan explained many things that need to be paid attention to when going out.

"Got it, Gray Old!"

However, Gray Yuan mentioned in his words that he still had to go to the Imperial City, which made him a little surprised, but he still had some benefits promised by Emperor Qin before, and it was time to collect them.

"Gray Elder, why is there only a teleportation array in the Imperial City?"

This information he had absorbed from all the knowledge of the Library Pavilion, and there was no mention of it.

"Well, it's a means of control of the Blue Leaf Empire, maybe there is a problem with some funds, after all, the resources required to set up a teleportation array of that level are very terrifying! And it's not ordinary people who are qualified to use it!"

Gray Yuan explained.

This is in line with common sense, after all, the distance from Xuanyue to the Blue Leaf Empire is hundreds of millions of miles, if Cao Yu flies over, it is estimated that it will take a few years, or continue to fly.

"You go and clean up, and at the same time explain to Buwei! This girl will keep her alive as long as I still have the breath, don't worry!"

"The grace of the gray old man, toothless and unforgettable!

After Cao Yu saluted, he planned to retreat.

Suddenly, Gray Yuan stopped him again and stared at Cao Yudao solemnly.

"Boy, live well!"

"Hmm!!"

Cao Yu knew that this trip would definitely be difficult, not to mention those precious medicinal materials, which needed to be found in an extremely unique environment.

Even if some extra-large cities have them, they need sky-high spirit stones to buy.

Of course, if it can be bought directly somewhere, he is naturally happy to spend money to buy it directly.

After all, compared to the life of one's beloved, money is nothing more than something outside the body, and there will always be a chance to get it again.

Leaving the gray Yuan hut, Cao Yu flew straight to Tian Buwei's courtyard.

Yesterday's battle had razed it to the ground, and I don't know if Tian Buwei was still there, Cao Yu was also a little uncertain, so he took out the sound transmission jade talisman and asked.

After getting Tian Buwei's affirmative answer, he continued to move forward.

A moment later, Cao Yu appeared above Tian Buwei's courtyard.

At this time, the courtyard has been completely rebuilt, and it is exactly the same as before, but it has been completely renewed.

In the small courtyard in front of the door, Tian Fuyun sat on a stone bench, holding his chin, looking at the medicine garden in front of him, which was originally full of flowers and plants, and at this moment there was only a piece of loess left.

When Cao Yu landed outside the courtyard gate, Tian Fuyun was still in a daze.

"Nephew Tian, what do you want! Come and open the door for me!"

"Ahh...h Uncle Cao, you're here!!"

Tian Fuyun didn't know what he was thinking, and only when he heard Cao Yu's voice did he react.

Seeing that it was Cao Yu, his face was instantly full of joy, and he ran over to open the door with a smile like a little spirit magpie.

"Uncle Cao, are you here to find your father?"

Tian Fu opened the door and looked at Cao Yu with a smile on his face.

"Can't I come over to see you, nephew?"

Cao Yu smiled mysteriously, and his eyes stared at Tian Fuyun all the time.

"Uncle Shi, why are you staring at people like this?"

Tian Fuyun is a yellow flower girl, how could she have been stared at like this.

"Haha! I want to take a good look at my nephew again, otherwise I'm afraid I won't see him for half a year~"

Cao Yu laughed, and one sentence resolved the embarrassment.

"Ah, uncle, are you going out for a long time? Let's go sit and talk first, it's not good to stand here, and my father thinks I'm snubbing my uncle!"

When Tian Fuyun heard that Cao Yu was going out for half a year, his face was a little reluctant, but he disappeared in a blink of an eye, and at the same time pulled him in to sit inside.

"This matter is a long story, I went out this time, mainly to find a cure for Qing'er and ask a saint-level alchemist to help!"

As soon as Feng Qing'er was mentioned, the smile on Cao Yu's face disappeared.

"How is Sister Qing'er doing now?"

Tian Fuyun experienced yesterday's thrilling incident, and now he still remembers it vividly, originally he thought he was going to be humiliated.

If it really reaches that level, it will inevitably leave and no longer remember the short rest of his life in the red dust.

Just doing that would break his father's heart.

Fortunately, Cao Yu appeared at the last moment to save her, and her father told her about it afterwards.

So her gratitude to Cao Yu now can be said to be almost a personal promise.

"It's the same as before, unconscious, and I can only rely on the gray old man to inject true qi every day to continue my life!"

"Sister Qing'er is really a miserable person, Uncle Shi, you must find medicine and save Sister Qing'er!"

Tian Fuyun looked at Cao Yudao with a begging face.

"I don't need to say this, I'm more anxious than you, you can rest at home with peace of mind, I'm going to leave tomorrow."

Cao Yu patted Tian Fuyun on the shoulder and said.

"Uncle Shi, can you not call me my nephew, I feel so angry!"

Tian Fuyun's face was slightly red.

"Haha, then how can I call you! Is it the same as your father, add you Yun'er?"

Cao Yu was made to laugh and cry by Tian Fuyun's shy appearance.

"Yes, it's so kind! I guess Daddy won't mind."

Tian Fuyun's face was full of joy.

"Okay! I'll call you Yun'er, and you'll call me Brother Yu! Let's talk about each other, after all, I'm the same age as you! I'll call you Uncle every day, and I'll be called old by you."

"Mmmmmmmmmm

"By the way, Yun'er, I saw some books in the Library Pavilion that may be related to your physique, can you let me see your body?"

Cao Yu suddenly thought of saving Tian Fuyun, and he needed to check his physical condition first, and asked directly.

It's just that these words have a different taste to Tian Fuyun.

"Brother Yu, are you looking here, why don't you go into the house!"

As he spoke, Tian Fuyun's face was flushed, and his head was about to be buried in his chest.

"Uh... This!"

Cao Yu didn't react for a while, what he meant was just to probe the internal situation of Tian Fuyun's body, not that kind of look.

"Yun'er, you may have misunderstood, I just need to pass through my hand"

"Ahh

Tian Fuyun realized that he had misunderstood at this moment, and immediately covered his face and ran into the house, he was extremely shy.

Cao Yu couldn't smile bitterly when he saw this, but after a while, Tian Fuyun's voice came from inside again.

"Brother Yu, you come in and drink tea!"

Cao Yu shook his head, not knowing what was going on in this woman's head.

At this moment, all the furniture in the room was new, and Tian Fuyun saw Cao Yu come in and poured him a glass of water, so he tilted his head to the side.

It must have been the embarrassing side just now that made her very embarrassed.

Pulled a stool and sat down, Cao Yu said indifferently: "Yun'er, come, stretch out your hand, I'll help you take a look!"

"Brother Yu, do you still practice medicine?"

Tian Fuyun was no longer pretentious, and generously put his hand in front of Cao Yu.

"Hehe... Just a little bit of it."

In fact, Cao Yu absorbed all the books in the library pavilion, and he was much sharper than those little doctors in the folk for medicine.

It's just that everything he knows is limited to theory, and there may be a big gap in practice.

The reason why he wanted to investigate Tian Fuyun's body was to determine whether it was similar to the book.

Cao Yu's hand lightly rested on Tian Fuyun's weak and boneless white jade hand.

True qi poured in, and suddenly Tian Fuyun felt refreshed, and couldn't help but let out a light trembling sound

"Ahh

Where did Cao Yu, who was strong in blood, hear such a temptation, and suddenly a burst of fire broke out in his lower abdomen.

But where can the current situation be presumptuous, and the ninja will continue to investigate.

The aura emanating from Tian Fuyun's body seemed to be extremely vicissitudes and ancients, very similar to the situation described in that book.

Cao Yu withdrew her true qi, and in a blink of an eye, the true qi in her body dispersed like a deflated ball.

Sure enough, it really looks like it's really Gu Xuanti!

Cao Yu saw this situation and knew it in his heart.

Tian Fuyun was originally still immersed in the comfort of the true qi, but he was disconnected for a while, and he felt that he couldn't stop.

At this moment, a figure suddenly appeared outside.

"Yun'er, junior brother, what are you doing here?"

It was Tian Buwei, from Tian Buwei's point of view, Cao Yu was holding Tian Fuyun's hand, and Tian Fuyun showed an expression of extreme enjoyment on his face.

"Ahh Uncle Shi gave me a doctor."

When Tian Fuyun saw his father coming back, he withdrew his hand like lightning, and explained with a red face.

Tian Buwei looked incredulous, looked at Cao Yu's evil smile, and scolded Cao Yu hundreds of times in his heart.

I treat you as a brother, and you want to soak my daughter!!

"Senior brother, I'm checking Yun'er's body, and I'm also preparing for collecting medicinal herbs or something in the future!"

Cao Yu didn't dare to stand up, if Tian Buwei found out his embarrassment, he wouldn't be able to wash it away by jumping into the Yellow River!

Tian Buwei didn't believe it, who were you fooling, the little girl's face was red when she was fooled by you.

However, he didn't want to dig deeper, after all, even if Cao Yu and Tian Fuyun were together, he was still more happy.

In terms of talent, appearance, and strength, Cao Yu is a leader of the same age, and he is very satisfied with this son-in-law.

"Haha! It's okay, it's okay, check it when you have time!"

Tian Buwei laughed for the old disrespect.

"Senior brother, you came here to say goodbye!"

"Well, I'm going out to see my brother, and I don't know how long it will take to come back!"

"Be careful! Senior brother is incompetent and can't give you anything, but this will always be your home!"

Tian Buwei knew that Cao Yu was not lacking anything, and with the martial arts he had just performed outside, he knew that Cao Yu was estimated to have benefited from Elder Taishang.

"It's okay, Senior Brother has helped enough!"

"By the way, Senior Brother, why did the people of the Star Dou Kingdom suddenly come to provoke us this time!"

Cao Yu remembered what happened before and wondered.

Under normal circumstances, the Star Dou Country is tens of millions of miles away from here, and whoever has nothing to eat too much will run so far to pretend to be forced.

"You don't have to think about it to know that it's the Great Elder, this wolf-hearted thing!"

"He's here to fight you!"

Cao Yu probably understood, and it was estimated that the Great Elder had been trying to defeat Tian Buwei in front of the people of the academy, so he spent a lot of money to find the monks of the Star Dou Kingdom.

"Haha, thanks to you at this point! That old thing probably can't sleep at night now!"

"Where do you say that?"

"That old man has the character of retribution, and he will definitely settle accounts with Li Xuanqing's old thing first, but you are also very dangerous, if you go out this time, if you don't have to, don't go to Star Dou Country!"

Tian Buwei said with some concern.

"Well, I understand! The people of the Li family have attacked me many times! I must not let them have a good time!"

Cao Yu thought of the people of the Li family, and suddenly became indifferent.

"There's no urgency in this matter, when your strength is enough, turn over the matter!"

Tian Buwei comforted.

"Okay, it's not too early, I'll go back first, Yun'er, senior brother, take care!!"

"Senior brother, take care!"

"Brother Yu, you must come back safely!"

Cao Yu said goodbye and the two went back to their courtyard to cultivate.
